It's part of a natural light spectrum, which disturbs the circadian rhythm and causes sleeplessness, headache and bad eye health. Unlike red light night shade, screen light bluelight blocks the secretion of melatonin, sleep hormone, and causes restlessness. Retinal neurons are in danger if night filter anti glare is not used after twilight for eye care.

Saving and editing night mode filters - Create and edit a night shift filter to rest your tired eyes from screen light or make a set of night filters to protect eyes, fix circadian rhythm, sleeplessness, insomnia and lack of melatonin after twilight.

Dimming below system minimum - Use "Dim" night screen option to protect eyes from natural light blue rays. It's best for good eye health and chronic headache relief during night reading because it gives a night shade warmlight in form of a night light.

Temperature customization - Use "Temperature" palette to set a warmlight (night mode) or cooler tint to your blue light filter. Twilight looking red light colors are recommended as a bluelight flux filter for tired eyes and used as a night shift for eye strain, chronic migraine relief, and sleepless restlessness.

- Automatic filter schedule - Choose the times in which the anti glare night mode will shift on and off to improve eye health. Ensure that blue light filter is always turned on after twilight to prevent cataract and fight insomnia and restlessness.
